Twenty-eight patients with intradural inflammatory disease of the spine were studied in order to characterize the MR imaging findings of infectious and inflammatory conditions. Patients were categorized according to the spinal compartment involved. Among the 12 patients in the intradural extramedullary group, unenhanced scans were either normal or nonspecific while contrast-enhanced scans were ...

AIM Intraoperative neurophysiological monitoring (IONM) monitors the functional integrity of critical neural structures by electrophysiological methods during surgery. Multimodality combines different neurophysiological methods to maximize diagnostic efficacy and provide a safety margin to improve the outcomes of spinal surgery. Our aim was to share our intraoperative monitoring experiences wit...

Two sisters, ages 37 and 26 years, developed bilateral acoustic neuromas and multiple intracranial meningiomas. Their mother and two other siblings also had bilateral acoustic neuromas. During a routine MR study of the brain of the older sister, an abnormality (possibly a mass) was found at the cervical medullary junction. This patient had no symptoms referable to this area, and postoperative c...

We report a case of a spinal intradural capillary hemangioma. On MR images, a well-circumscribed intradural mass was detected at the T8-T9 level. The signal intensity of the mass relative to the spinal cord was isointense on T1-weighted images, hyperintense on T2-weighted images, and showed homogeneous, strong enhancement on contrast-enhanced T1-weighted images. The mass had both extramedullary...

BACKGROUND Solitary bone cysts (SBC) are benign, tumor-like lesions, which most frequently occur in the proximal metaphyseal-diaphyseal region of the humerus and femur of children and adolescents. The lack of a clear pathoetiology has impeded the development of treatment strategies. Up to date there is no consensus or official guideline for when and how treat SBC. The purpose of this study was ...

A 21-year-old woman presented with an intramedullary spinal cord germinoma and a history of gait disturbance and elimination disorder. Magnetic resonance (MR) imaging demonstrated two isolated lesions, one located within the medulla between T9 and T11, and another at the cauda equina (L2 to L3 levels). After partial reduction of the intramedullary mass, histological findings revealed that the t...

Intramedullary tumors affecting the entire cord from the cervicomedullary junction to the conus are termed "holocord tumors". Ependymomas are the most frequent intramedullary tumor in adults. Holocord ependymoma is an exceedingly rare condition. An extensive review of the literature revealed that only five other cases have been reported. We report the sixth case of holocord ependymoma. In this ...

PURPOSE The management of proximal femoral deformity in fibrous dysplasia (FD) is a challenge to the orthopaedic surgeon. The purpose of this study was to analyze the various presentations of FD of proximal femur and the results of the various treatment modalities for the same. METHODS This is a retrospective cohort study of 23 patients (24 femora) with FD who underwent surgery for the proxim...

Intramedullary spinal cord metastasis (ISCM) is an infrequent lesion of systemic malignant tumors, and the most common primary sources of ISCM are lung and breast cancers, as well as melanoma and lymphoma. Patients with ISCM usually accompany with rapidly progressive neurological compromise and the prognosis of ISCM is poor. We present a case of a 40-year-old male with a history of parotid glan...

BACKGROUND Cervical myelopathy (CM) is a clinical diagnosis that may be associated with hyperintense areas on T2-weighted magnetic resonance imaging (MRI) scan. The use of contrast enhancement in such areas to differentiate between neoplastic and degenerative disease has rarely been described. CASE DESCRIPTION We present a 41-year-old female with a 5-month course of progressive CM. The cervic...
